The present study was undertaken to estimate genetic diversity and reveal population structure of Hilsa shad (Tenualosa ilisha) from two large river ecosystems, the Padma Meghna Bangladesh using mitochondrial control region (D-loop region). Fin tissue samples 60 individuals were collected (ChapaiNawabgonj) River (Chandpur). DNA extracted D-loopof mtDNA amplified, purified sequenced. A total 35 ...
در این پژوهش تغییرات بافتی آبشش و کلیه ماهی صبور به عنوان دو اندام اساسی و حائز اهمیت در فرایند تنظیم اسمزی در طول مهاجرت از خورموسی به رودخانه های کارون و بهمنشیر مورد مطالعه قرار گرفت. نمونه برداری از خلیج فارس و رودخانه های کارون و بهمنشیر از هر ایستگاه ۱۰ قطعه با خصوصیات زیست سنجی مشابه از نظر اندازه و وزن صورت گرفت. پس از فیکس کردن نمونه های بافتی در محلول بوئن و طی مراحل روتین بافت شناسی،...
